"I'm Just a Lucky So-and-So" is a 1945 jazz standard composed by Duke Ellington with lyrics by Mack David. It was recorded by Duke Ellington and His Orchestra with Al Hibbler on vocals on November 26, 1945 in New York, and released as a single in early 1946. The tune is a vocal jazz number about gratitude, lasting about 3 minutes and 13 seconds. The original recording showcases Ellington's arranging, with Johnny Hodges on alto sax and a rich horn backdrop, and it helped establish the song as a jazz standard. Notable later versions include Ella Fitzgerald's 1946 Decca recording and Louis Armstrong with Duke Ellington on Together for the First Time (1961). Other artists such as Wes Montgomery, Diana Krall, and Sarah Vaughan have also covered it, keeping the song alive in the jazz repertoire. It appeared on singles and later on compilations rather than first as a dedicated album, and has been featured on releases like Ella Fitzgerald Sings the Duke Ellington Songbook (1958).
